Definitions
- the present invention relates to the sector of refrigerating machines and the control and operation thereof.
- the present invention relates to the testing of the functional stability of a controller of refrigerating machines such as chillers, deep freezers and bottle coolers and in general machines used in the HVAC-R sector.
- testing method according to the present invention is applicable to isothermal and adiabatic humidification machines, air conditioning machines and heat recovery machines.
- any reference to a refrigerating machine, in connection with the present invention is to be understood as including the reference to such machines.
- the controller will have a reduced processing capacity, as specified in more detail below, and will be unable to perform the recording of data.
- a conventional controller has a series of inputs and outputs.
- the inputs are intended for connection to active and passive devices such as temperature, humidity and pressure probes.
- the outputs are intended to be connected to devices able to set or modify the operational state of the refrigerating machine and may be of the digital or analog type.
- the controller is configured to perform cyclically an algorithm for checking the refrigerating machine, which, on the basis of the signals obtained from the inputs and the status variables, sets the signals at the outputs.
- control of the refrigerating machine namely execution of the algorithm, requires a time equal to about 30-50 ms.
- Control is therefore performed as a discrete signal, namely a sequence of finite states which is repeated every T ms.
- the software modifications may be for example intended to implement new functions of the algorithm for the control of further components or for the management of new inputs or communication devices.
- the hardware modifications may relate to the modification or replacement of components of the refrigerating machine in order to improve the performance thereof or restore the functionality thereof in the event of maintenance.
- the task of the present invention is therefore to propose a method for testing the functional stability of a controller of a refrigerating machine which is able to detect in good time a possible regression condition in a refrigerating machine.
- an object of the present invention is that of providing a method for testing the functional stability of a controller of a refrigerating machine which is able to detect in good time a regression of the system in the case where the controller has very limited processing capacities.
- a further object of the present invention is to propose a method for testing the functional stability of a controller of a refrigerating machine which is reliable also in the case where modifications of the refrigerating machine result in a variation, even substantial in nature, of the execution time of the control algorithm.
- Figure 1 illustrates the control cycle of a controller of a refrigerating machine.
- Figures 2 and 3 illustrate, respectively, a recording step and an execution step of a testing method according to the present invention.
- Figure 4 shows a simplified diagram of an example of a preliminary setting step of a testing method according to the present invention.
- the refrigerating machine may be a deep freezer or bottle cooler and the controller may be for example a parameter-based controller designed for such applications.
- each of said control cycles may involve, in sequence, the following operations:
- the testing method may involve an operation of connecting the controller to a diagnostic unit for exchanging data therewith during operation of the controller.
- this connection operation may involve a connection of said diagnostic unit to the inputs and the outputs of said controller in order to transmit data relating to said input variables and said output variables, as well as said status variables, to said diagnostic unit.
- the diagnostic unit may consist of a PC.
- the said testing method may involve, during operation of the refrigerating machine, the implementation of a recording step 100 and a subsequent execution step 200 which may be carried out by the diagnostic unit.
- the operation D may count the control cycles which are performed during the recording step and, in particular, associates with the recording cycle identifier IDR a progressive value, which in the case of Figure 2 will vary from 0 to n.
- progressive value may be understood as meaning a natural number, the value of which is defined by the number of control cycles counted starting from the start cycle.
- control cycle identifier IDT in which the reference data set was recorded may therefore be associated with each reference data set recorded in operation F.
- the execution step 200 may involve in sequence: - an initialization operation H in which, prior to the execution of the operation A, the current values received by the controller for the input variables and for the status variables are replaced by the values of the input variables and the status variables of the reference data set which was recorded in the operation F carried out in said start cycle cO; wherein the control cycle in which the operation H is performed is assumed as an initialization cycle; in this way, upon execution of the first operation A carried out during the execution step 200, the controller will adjust the refrigerating machine on the basis of the same values of the input variables and the status variables which were detected during the start cycle of the recording step;
- control data set which comprises a set of current values of the output variables
- execution step 200 also involves associating with each control data set the execution cycle identifier IDE in which the control data set was recorded;
- the testing method according to the present invention may comprise a comparison step in which the following will be compared:
- the recording step 100 may involve operation D being repeated at least once following operation F, and the execution step 200 may involve operation I being repeated at least once following operation J and/or following operation K.
- the controller may comprise a memory in which data relating to the input variables and the status variables are stored in each control cycle.
- This data will have sizes and addresses in the aforementioned memory which remain fixed during the control cycles.
- the testing method may further comprise a preliminary setting step which precedes the recording step 100 and which involves:
- the operation F and the operation J may each involve:
- the request for data in operations F and J, by the diagnostic unit to the controller, and the transmission of the requested data from the latter to the former may employ, respectively, 2 bytes for the request and 1 Kbyte for the response.
- the transfer of the aforementioned data may be performed by envisaging that the preliminary setting step may comprise the organization of said data in a plurality of pages.
- the operation N and the operation O may, in this respect, involve respectively the requesting and the transmission of one of said pages, operations N and O being carried out cyclically until the transmission of all the pages from the controller to the diagnostic unit is completed.
- the controller has a limited hardware capacity as in the case where it has a RAM with a capacity substantially of between 32 KB and 256 KB and/or a ROM with a capacity substantially of between 128 KB and 2048 KB and with a CPU clock of between 20 MHz and 200 MHz with serial communication port.
- the recording step 100 and/or the execution step 200 may each comprise a standby step 300.
- the standby step 300 consists in a delay in starting of the cycle of operations D- F and/or H-K and, in general, depending on the type of refrigerating machine, may also not be present.
